Lithuanian lightweight Evaldas Petrauskas has produced a punishing performance to send Turkey's Fatih Keles packing from London 2012.

Petrauskas marauded forward from the first bell, unleashing wave after wave of attack.

His defence looked impenetrable, tucking up tightly before moving into range and bombarding his opponent with venomous shots.

The Lithuanian had opened up a four-point gap after two rounds and by now was firmly in the driving seat.

Keles could do nothing to repel Petrauskas, who ran out a 16-12 winner.
